When changing the account language, the language of the chat window changes to the same as in the account language. If you set the account language, then the chat window (and the pre-chat form too) on the site is displayed in the same language, that is, we cannot make a Turkish window for the Turkish version of the site, an English window for the English version, etc. It is proposed to make the chat window language setting inside the "source/channel" setting. In this case, several sources can be added to a multilingual site and each can be assigned its own language, and the language of the admin panel would not affect how the chat window is displayed for clients.
